What is div tag? What is it used for?

Question

What would happen if I don't use it? Is there any alternative to div tag?

Answer 1

Div is a block level element. use it when it doesn't make sense to use other elements. like for using a wrapper for other elements. Or to divide your content.

<div></div> = block element. All the block elements are alternative to div tag. will not float.
